ЛИТИЙ-ИОНДЫ АККУМУЛЯТОРЛАР СЕПАРАТОРЛАРЫ: ҒЫЛЫМИ ШОЛУ ЖӘНЕ БОЛАШАҚ БАҒЫТТАР

Abstract

The separator, being one of the key components of lithium-ion batteries, plays an important role in ensuring their safety and electrochemical characteristics. It is a thin porous membrane that prevents a short circuit between the cathode and the anode, as well as providing ion transport. Although the separator is not directly involved in electrochemical reactions during battery operation, it has a direct impact on its safety and performance. In this regard, the requirements for separators are extremely high and continue to be the subject of active research. Despite the fact that researchers' attention to the development of new separators has increased significantly over the past decade, the history of their creation dates back to the 1970s. Based on the world scientific literature, this literary review examines the stages of development of separator manufacturing technologies, their evolution, basic requirements and characteristics, as well as modern types of separators. Special attention is paid to the quantitative analysis and consideration of key indicators and criteria important for the development of multifunctional separators of the next generation.
